What is the function of HDL cholesterol in the body?

• A. To promote weight gain
• B. To carry cholesterol from the arteries back to the liver
• C. To raise blood pressure
• D. To store fat

Answer: (B)

HDL cholesterol, often referred to as "good" cholesterol, plays a crucial role in cardiovascular health by transporting cholesterol away from the arteries and back to the liver. This process is essential because it helps to reduce the buildup of cholesterol plaques in the arterial walls, which can lead to atherosclerosis and increase the risk of heart disease and stroke. The liver can then process this cholesterol and excrete it from the body, thus maintaining a healthy balance of lipids in the bloodstream. This action of HDL is integral in supporting heart health and preventing cardiovascular diseases. While other options mention aspects related to body function, they do not reflect the protective and vital role that HDL cholesterol plays in managing cholesterol levels and promoting cardiovascular health.
